PATENT SHINGLE-NIACHINE.

SPECIFICATION forming part of Letters Patent No. 271,407, dated January30, 1883. Application led September Q9, 1882. (No model.)

To all whom it may concern:

Be it known that I, WlLLIAM A. BRADLEY, ot' Oshkosh, in the county ot'Vinnebago and State ot' Visconsin, have invented a new and usefulImprovement in Shingle-Machines, of which the following is a full,clear, and'exact description.

My invention consists ot' improvements in the driving-gear, also in thebolt-dogging apparatus, and also in the bolt-setting apparatus ot'shingle-sawing machines, as hereinafter fully described.

Reference is to be had to the accompanying which similar letters ofreference indicate corresponding' parts in all the figures.

Figure l is a plan view of a shinglemachine constructed according to myinvention. Fig.

2 is a side elevation with some of the parts in section. Fig. 3 is atransverse section on the line x x, Fig. l. Fig. 4 is asection ot' theboltcarriage on the line y y, Fig. 3; and Fig. 5 is a section of thesettingapparatus, taken on theline z z of Fig. 3.

For the purpose of simplifying the drivinggear and preventing` all slackand lost motion of' the carriage in running and on vthe backstroke, Ipropose to dispense with toothed wheels altogether and employ abe1t-pulley,a, on thesaw-arbor z', for the first part ofthe rewhichpulley the driving-belt b works onto the large pulley d of thecounter-shaft e, which carries a small driver,f, from which the belt gworks onto the large pulley h ot' the feed-shaft c. A tightener, kl m,will be used with the belt b for producing the necessary tension todrive the feed-gear, and for slackening the belt to allow the feedvtostop, when required, without stopping the saw-shaft, on the top ot'which the saw jis mounted by the collar It. The main belt runs on thepulley a2 for driving the saw. Y

Only a single machine is shown in thiscase; but by the extension of theframe to the left hand of the main feedshaft, and the duplicationthereon ot' the mechanism shown, except shaft c, the machine will bemadedouble, which is the intention in practice.

The feed-shafts c and e and thc saw-arbor t' are arranged in suitablesteps, n, in the bedtimbers ofthe frame; and to operate the boltcarriage0 for sliding itfor Ward and backward in the guidesp to feed the boltsto the saw, I propose to apply the eccentric q to the upper end of thefeed-shaft c to work'the yoke-lever s, fixed on a pivot at t to vibrateso as to reciprocate the carriage by its swinging end n, to which the4carriage is `connected by a suitable rod, c. This makes asmooth-working device, entirely t'ree from shocks and jars by thebacklash of slack gears.

For dogging the bolt I use a sliding dog plate or bar, w, xed in guidesx in one end ot' the carriage, with a spring, y, to cause it to grip andhold the bolt, and also with a rod, z, forming a support to the spring,and having a stud, a', by which the dog is automatically detached fromthe bolt for resetting said bolt by the inclined arm b', along which thestud a is moved bythe carriage in the latter part of its back-stroke, soas to free the bolt from the dog and allow the bolt to fall on the tablec', on which it rests and slides until by the forward motion of thecarriage the stud a passes oft' from the inclined -arm b', and thespring y again causes the dog-bar to grip the 'end of the bolt. Said barmay have any suitable ar,- rangement ot' spur studs or points topenetrate the block sufficiently to insure a firm hold. Thus the boltsare automatically shifted and set for the successive cuts. The object oflocati ng the dog slide guides on the top of the carriageis to placethem and the spring and stud so far above Athe saw that they will not beclogged by the sawdust.

In order to cause the resetting of the bolts, so as to alternately cntbutts and points at the respective ends of the bolts, lthe bars c,forming the table whereon the bolts fall and rest in the resettingoperation, are mounted on the bars d', pivoted at the center ot thetable, at c', to the head f ot' vertical standard g', said bars rangingtherefrom toward the respective sides of the machine, and resting, whenin their normal position, on the temper-screws h at their outer ends,said temper-screws being tted adjustably in the cross-bar i', supportedon the standard g by the collar j. The respective sides of the tablethus supported and pivoted may therefore be raised and lowered to tiltthe bolt, or, rather, cause it to assume an inclined position when itfalls, one end falling lower than the other; and in order to alternatelyshit't the respective sides ofthe table for alternating the butts andpoints of the shingles the bars d are formed with inclines 7c on thelower side, and wedges l are mounted on a sliding bar, m', under them,which are shifted each time the carriage goes forward by the zigzagearn-disk n', which works between the studs o on said bnr m, and isworked by the catch-pawl p', pivoted to the carriage so as to engage oneof the stud-pins q of the disk each time the carriage goes forward tothe saw, and shifts the canrdisk to the extentof one of the inclinesofthe disk, thus reversing' the movement of the slide at each motion ofthe carriage and alternately lifting the opposite sides ofthe table c.The catch-pawl p is provided with a lever handle, t', by which to liftit up so as to set the pin u under it, and hohl it out of engagementwith the disk n when it may be desired to cut the shingles in uniformthickness. The wedges l are slotted for their fastening bolts w', inorder that they may be shifted forward and backward along the bar toraise the sides of the table more or less, to vary the thickness of thebutts and points of the shingles as may be required. The standard g is Yadjustable by the screw-nuts a," and supporting-bar y to vary the heightof the table.

i Having thus described my invention, I claim as new and desire tosecure by'Letters Patentl. In a shingle-machine, the combination, withthe saw-arbor i, provided with the pulley a., and the feed-shaft c,provided with the pulley h, of the counter-shaft e, provided with thepulleys df, the belts b g, and the belt-tightener It lm, substantiallyas and for the purpose set forth.

2. In a shingle-machine, the combination, with the boltcarriage 0, ofthe tablec d', composed of two parts hinged together, and means,

substantially as herein shown and described, i'or alternately raisingand -lowering the sides of the table, as set forth.

3. In a shingle-machine, the combination, with the table c d', composedof two parts hinged together and having inclines k' on its undersurface, of the shifting bar m', provided with the wedges l', and means,substantially as shown and described, for operating said shifting bar,as set forth.

4. In a shingle-machine, the combination, with the table c d', composedof two parts hinged together and having inclines h on its under surface,of the bar i, the temper-screws h', the shifting bar m,provided withwedges l', and means, substantially as shown and described, foroperating said shifting bar, as set forth.

5. In a shingle-machine, the combination, with the adjustable standardg', provided with the head f', of the table c d', composed of two partshinged together and pivoted at its center tothe said head, and thetemper-screws h', substantially as and for the purpose set forth.

6. In a shingle-machine, the combination, with the table c d', composedof two parts hinged together and provided with the inclines lr, of theshitting bar m', provided with the wedges l and the studs o', the zigzagcamdisk n', provided with the pinsq,and the pawl p', substantially asand for the purpose set forth. 7.
